N2 - This study is focused on a new method to determine the thermo-electromotive force (thermo-E.M.F.) of a non-degenerate bipolar semiconductor taking into account recombination heat of non-equilibrium carriers, the non-linear temperature distribution with respect to position, and the existence of two different quasi-levels of Fermi for electrons and holes. The thermo-E.M.F. depends on both bulk and surface recombination processes, the bandgap, the length of the sample, and the thermal conductivity. Moreover, it can be equal to its classical expression for particular values of diffusion length, characteristic length related to surface recombination, and the thickness of the sample. The results also show that there are several possibilities to cancel the contribution of the holes on the thermo-E.M.F. by giving specific quantities to the three previous lengths.
